You need to import the function using:

            [DllImport("user32.dll")]
            public static extern int SendMessage(
                  int hWnd,      // handle to destination window
                  uint Msg,       // message
                  long wParam,  // first message parameter
                  long lParam   // second message parameter
                  );

 

and define the message that you want to send like:

public const int <WM_YOURMESSAGE> = <yourvalue>;

 

and then call SendMessage like any other function.
